<p>Provided is a method for integrally providing electronic books. Two or more electronic books can be organically integrated by determining the relation of list items of two or more electronic books using a pre-constructed knowledge system and creating an integrated list based thereon. Thus, a learner can read two or more electronic books without a sense of difference as if the books were a single copy from the beginning, and can save time and effort which are unnecessarily wasted upon learning while comparing books which have similar contents and subjects.</p> |
